in thread Perl Upgrade

Perhaps in the general case, but Abigail's answer in this thread seems to indicate that 5.8.3 and 5.8.0 are not binary compatible (unless they rolled back the change they made in 5.8.1)

    Incompatible Changes
        For threaded builds for modules calling certain re-entrant system calls,
        binary compatibility was accidentally lost between 5.8.0 and 5.8.1.
        Binary compatibility with 5.8.0 has been restored in 5.8.2, which
        necessitates breaking compatibility with 5.8.1. We see this as the
        lesser of two evils.
    
        This will only affect people who have a threaded perl 5.8.1, and
        compiled modules which use these calls, and now attempt to run the
        compiled modules with 5.8.2. The fix is to re-compile and re-install the
        modules using 5.8.2.
